为了高效去除制革废水中的Cr（Ⅵ）,实验采用粉末活性炭包埋蜡质芽孢杆菌（Bacilluscereus）制成固定化细胞颗粒,并探讨了该颗粒去除Cr（Ⅵ）的效果。结果表明,在pH值5.0、温度37℃、Cr（Ⅵ）初始浓度小于10mg/L、颗粒用量0.5g/mL左右时,Cr（Ⅵ）去除率较大;在最优条件下,固定化细胞颗粒处理Cr（Ⅵ）的效果比未加菌体的固定化颗粒和Bacillus cereus单独处理时的效果都好。研究表明,固定化Bacillus cereus细胞颗粒可以作为一种新的生物材料,处理制革废水中的Cr（Ⅵ）。

In order to remove Cr（Ⅵ） in tannery wastewater efficiently,Bacillus cereus is embedded in powered active carbon,which can form immobilized granule.And the removal effect of Cr（Ⅵ） by the granules is discussed.The results show that the removal rate of Cr（Ⅵ） is the highest at pH5.0,37 ℃,less than 10mg/L of Cr（Ⅵ） initial concentration and 0.5g/mL of the immobilized granule;at the optimum condition,the effect of Cr（Ⅵ） removed by immobilized granule is better than either immobilized granules without the Bacillus cereus or single Bacillus cereus.The experiments demonstrat that the immobilized Bacillus cereus can be selected as a new biomaterial to remove Cr（Ⅵ） in tannery wastewater.
